Be itknown that I, GUsmr TnoLIJn- BONDE', a citizen of Sweden, residingfat Trolleholmbinl the county of M'almohus,

Sweden, have 'invented a new and} useful.

Improvement infApp'aratus, for Airingof Stored Corn, "of which the following is a;

specification;

com 7 1n granarles ,or elsewhere.

A number of ,dlffere of corn that is kept storedlduring a long time have already been proposedj 'By' these 'devices it has however been impossible to PIG- vent, that the corn, notwithstandingthe supply ,of air, is damaged and forms lumps or clods, thus making' i't dil'licultlto empty the storehouse, especially when} thecorniskept'in g ranaries, as the lumps yvill prevent the corn from flowing; outfl by its lo wn weight. These disadvantages are due partly to an 'inappropriateform and: partly to an unsuitable position of the nozzles I through I which the air is supplled. It has been proposed in granar'ies to arrange the air inlet combined with the outlet of corn at the lower part of the bottom of the granary, but the single air inlet thus provided is inis just this form that makes the flowing out I more difficult. It is therefore inappropriate I to combine the air inlet with the Outlet of has corn, and this disadvantage is remedied-according to the invention by: making the air inlets independent of the outlet "openings for'the corn. In thisway the advantageis',

also gained that the necessary'number of "air inlets maybe provided and that they;

may be placed in right positions. It has also been proposed to arrange the air in lets without being combined with the outlet portant, as it is just at these walls where the corn is baking.- Also this drawback'is removed by the' invention bygiving the air inlets or nozzles such a form that the air currents'sweep over the bottom of the granary Specification fieaersracem;

The disks may be raised and lowered in relation to the bottom of the receptacle by meansc'of the screws, and thus the size of the air inlets may be varied for the supply of more or less air or for shutting ofi the supply of air totally incertain places. 7 In order to prevent the corn from impeding V edges of the disks the movement of the disks the latter are covered with a wire grating 6 (Fig; 4), so that the corn cannot penetrate under the and prevent their closing movement. V

' In Figs. 1' and-2 the invention is shown as applied to a corn receptacle with horizontal bottom, and it is evident that by this arrangement even a very thin layer of corn 7 maybe blown through efl'ectively just as well as a thickerzlayer. In order to obtain the. best possible result byusing the smallest possible number of nozzles these are placed in'rows in which the nozzles in one row are zigz a g inrrelation to the nozzles in the adj acent rows. 7 The same arrangementmay According, to Eig-B thenozzles are the same way as uniformly'distributed as possible in equal distances from each other over the wholeyconical surface and without being combined with other-openings in the saineQ Thusthey arequiteindependent of z the outlet openingf w hen' the nozzles are arranged in this way their number mayof different kinds of corn, it may be adapted to each separate case by regulatingor closing the disks. The nozzlesdescribed may ofcourse also be arranged in the vertical side walls of the receptacles if this is required, for instance in very highgranaries.

I claim as my invention; f

The combination with a corn or similar receptacle, having an air admission pipe leading there into, of a hood'overlying the end of'said pipe within the receptacle and having a cone shaped deflector arranged in line with and wholly beyond the pipe, and

a plurality of elements connected with the hood immediatelyadjacent the free edge thereof and beyond the air pipe, said elements having threaded connection with the receptacle and being operable the receptacle. 7 v

vIn testimony whereof, I have signed my from beyond name to this specification in the presence of two subscribing witnesses.
